SAFETY ATTACHMENT FOR FIREARMS.

Specification of Letters Patent.

Patented Nov. 7, 1916.

Application filed February 28, 191G. Serial No. 80,900.

To all whom it may concern Be it known that 1, JOHN Howano CARL, a citizen of the United States, residing at Gilroy, in the county of Santa Clara and State of California, have invented certain new and useful Improvements in Safety Attachments for Firearms, of which the following is a specification.

This invention relates to safety attachments for automatic firearms of that description in which all operations, except the actuation of the trigger for firing, are automatically effected by the energy of the recoil of the breech-closing part.

The object of this invention is to provide a demountable safety attachment for firearms which serves to lock the trigger, bolt and hammer, when in either closed or open position, by a single operation of the atta chment.

Another object is to utilize the pivot pin of the safety plate, as a guide for the magazine.

- A further object is the construction and location of the safety plate whereby it will cover the larger ends of tapering sear and hammer pins, to keep them in position within the firearm.

The invention is illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the firearm partly broken away, showing the safety at tachment in dotted lines pivoted to the side of the firearm. Fig. 2 is a side elevation of a firearm and safety attachment partly broken away to show the operation of the safety pins through the side of the firearm. Fig. 3 is a top view of the safety attachment. Fig. 4; is a top view of the trigger. Fig. 5 is a front view of the trigger showing the slot in which the safety pin lies. Fig. 6

is a side view of the hammer, showing the two notches adapted to receive the safety pin. Fig. 7 is an edge view of the hammer.

Referring to the drawings, 1 indicates the pistol grip, 2 the trigger, 3 the hammer, 4 the sliding bolt, 5 the frame, and 6 the barrel.

A plate 7, preferably flat, lies against one side of the frame 5 and is pivotally held thereagainst by a pin 8 which passes through the frame. One end of the pin 8 is integral with the plate and the other end is split toprovide spring arms 9, which normally bear against opposite portions of the frame when the pm is mserted in a hole 1n the side of the frame. he ends of the'arms 9 are provided with heads 10, which lie just outside of the frame, to hold the pin in position and also to serve as finger pieces when desirable to press the arms together, to remove the pin. A knurled member 11 is located on the outside and at one end of the plate, by means of which the plate is shifted by the thumb when so desired. Locking pins 12, 13 and 14 project from the inner face of plate 7.

The trigger is provided .with a notch 15 located a little below the top and at one side thereof, to receive the. pin 12. The locking pin 12 is inserted through a slot 16 in the side of the frame, and when the plate, carrying pin 12, is pushed up the pin will lie in the path of the shoulder formed above notch 15 on the trigger and prevent the trigger from being pushed back. is down and the pin 12 is in its lower position, the pin will lie in notch 15 and allow the trigger to be operated.

l hen the sliding bolt 'r in its forward or closed position, pin 3 is positioned through a slot 16 in the side of the frame, so that when the plateis in its upper position, the pin will lie directly behind the shoulder of the bolt and prevent it from being operated. When the plate is pushed down, the pin 13 will extend under the shoulder and allow the bolt to slide back. A recess 17 is provided in the sliding bolt to receive the locking pin 13,- when the bolt is in its rear or open position, and the plate carrying the pin is pushed in its upper position.

One side of the hammer has recesses 18 and 19 to receive the locking pin 11'- when the plate carrying the pin is pushed up by the finger piece 11. The recesses 18 and 19 are located so as to allow the pin 1 1 to lock the hammer in either cooked or closed position. The recess 19 is further positioned in the hammer so that when the pin is in locked position therewith, the hammer is forced a slight distance away from the firing pin.

The sear and hammer are pivoted to the frame by tapered pins 20 and 21, respectively. The plate 7 is of such a length and shape that when secured to the frame, it will overlap the larger ends of the pins 20 and 21 and prevent them from falling out.

The pivot pin 8 extends through the frame just behind the magazine 22 and serves as a rear guide and support for the magazine,

lVhen the plate thereby preventing the magazine from mov ing when in operative position.

hen the thumb piece on the plate carrying the locking pins is pushed to its up-- permost position, it will lock the trigger, bolt and hammer simultaneously, when the bolt is in either open or closed position, or when the hammer is in either closed or cocked position.

The plate carrying the thumb piece is positioned on the side of the frame so that it can be conveniently operated by the thumb when the hand grips the piston and is in position to operate the trigger.

Having thus described the invention, what I claim and desire to secure by Letters Patent, is

1. In a firing mechanism for firearms, the combination with the trigger, the sliding bolt and the hammer, of a plate pivotally secured to the firearm and provided with means for locking the trigger, the sliding bolt and the hammer simultaneously.

2. In a firing mechanism for firearms, the combination with the trigger, the sliding bolt and the hammer, of a removable plate pivotally secured to the firearm and provided with means for locking the trigger, the sliding bolt and the hammer simultaneously.

In a firing mechanism for firearms, the combination with the trigger, the sliding bolt and the hammer, of a plate carrying means for locking the trigger, the sliding bolt and the hammer, said plate having a split pin integral therewith adapted to pivotally secure said plate with the firearm.

i. In combination with a firearm, a safety device comprising a plate having locking means integral therewith and a pin projecting through the firearm adapted to provide a rear support for the magazine within the firearm and to secure the safety device to the firearm. V

In combination with a firearm, a safety devicesecured to the side of the firearm, comprising a plate having locking means integral therewith, said plate being positioned and arranged to cover the sear and hammer pins to secure said pins within the firearm.

(S. In combination with a firearm, a removable safety device comprising a plate having locking means integral therewith and a pin projecting through the firearm having one end integral with said plate and the opposite end split to form spring arms adapted to press outwardly against the frame when inserted through a hole therein, to pivotally secure said safety device to said firearm.

7. In a firing mechanism for firearms, the combination with the trigger, the sliding bolt and the hammer, of a plate pivotally secured to said firearm and provided with means for locking the trigger, the sliding bolt and the hammer,

In testimony whereof I have afiixed my signature in presence of two witnesses.
